The tiger beetles construct the turrets to protect the larva from dust after dust storms

 

 

 

 

6.
Extra Credit

The tiger beetles construct the turrets to keep the heat from the sun from entering

 

 

 

 

OBSERVATION - List a puzzling observation which inspired the causal question

CAUSAL QUESTION - Write a question, that if answered, would explain the phenomenon you observed

HYPOTHESIS - What is a testable explanation for the observation? (Stated as a fact)

PREDICTION - If the hypothesis is tested what specific outcome would you expect to observe? (Use the key words: will, should)

CONCLUSION - Based on your results, do you support or reject your hypotheses? Explain why. Also, propose an alternative hypothesis and/or future experiments?

The task is extension of the task "Why does this tiger beetle larva build a turret?". The part II has been completed which comprises data and hypothesis supported. Some of the conclusions are the turrets did not prevent or reduce the frequency of parasitoids; A heavy storm might not protect the larva despite having a turret but a light to moderate storm may aid in some sort of protection to the larva from dust, and the shade produced by the turrets attracted significantly more potential prey items than were available to turret-less larvae in the same habitat and an approximate count of the larva in the tunnels with turrets exceeded that of larva without turrets supported it.
